From 2cbe8b457ff066e3b11efe06a0d4d9fc4a34de45 Mon Sep 17 00:00:00 2001 From: Jesse Zhang <101612750+Nagi-ovo@users.noreply.github.com> Date: Fri, 19 Jun 2026 00:54:59 +0100 Subject: [PATCH] Document Opus 4.7 skeleton-watch exploded-view bug in run note Clicking Exploded View barely moves anything: animate() does const t = clock.getElapsedTime() then const dt = clock.getDelta(). getElapsedTime() already consumes the frame delta and resets oldTime, so the following getDelta() returns ~0 and dt is ~0 every frame, leaving the explode lerp (and crystal offset) effectively frozen. Gear rotations use t directly so the movement still runs. Bug documented, not fixed.

Known bug (not fixed): clicking 'Exploded View' does almost nothing — the parts stay assembled. Located in animate() (lines 933-934): const t = clock.getElapsedTime() followed by const dt = Math.min(clock.getDelta(), 0.05). THREE.Clock.getElapsedTime() internally already calls getDelta() and resets oldTime to now, so the getDelta() on the next line returns the gap between those two lines — effectively 0 — making dt≈0 every frame. The explode is driven by explodeAmount += (explodeTarget - explodeAmount) * min(1, dt*4), which barely advances when dt≈0 (measured ~0.0008 two seconds after the click; it would take minutes to open), so it looks broken; the crystal offset fails the same way. The gear rotations use t directly and are unaffected, so the movement keeps running." }, "contributor": "Nagi-ovo" }
